16
Q

What is stress?

A

Any external or internal condition that challenges the homeostasis of a cell or organism

17
Q

What are feedback loops?

A

How homeostasis is maintained

18
Q

What are the three parts of feedback loops?

A

Receptor, control center, and effector

19
Q

What does the receptor do?

A

Detects change in the environment

20
Q

What does the control center do?

A

Analyzes info from receptor and determines proper response

21
Q

What does the effector do?

A

Carries out a response

22
Q

What is a negative feedback?

A

When the body senses a change in the internal or external environment and wants to negate it- counteracts stimulus

23
Q

What is a positive feedback?

A

when stimulus triggers a self-amplifying cycle to continue the change rather than returning to normal

24
Q

How many organ systems are there?

A

11

25
Q

What are the 11 organ systems?

A

integumentary system (skin), skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems

26
Q

What is the function of the integumentary system?

A

Vitamin D synthesis, protect your body, regulate temperature, sensory detection, cell fluid maintenance

27
Q

What is the function of the skeletal system?

A

Provides structure, protects internal organs, produce blood cells, stores and releases minerals

28
Q

What is the function of the muscular system?

A

Helps you move, protects openings, help you stay warm

29
Q

What is the function of the nervous system?

A

Control feedback system, control body

30
Q

What is the function of the endocrine system?

A

Hormones

31
Q

What is the function of the circulatory system?

A

Move blood around the body

32
Q

What is the function of the lymphatic system/.

A

Maintain fluid levels by removing all fluids that leak out of our blood vessels

33
Q

What is the function of the respiratory system?

A

Move air in and out of your body and remove waste gases

34
Q

What is the function of the digestive system?

A

Break down food into nutrients

34
Q

What is the function of the urinary system?

A

Remove waste from your blood

35
Q
